Bio-Mass Fuels

Other fuels include bio-gas (methane) from anaerobic digestion of food and slurry waste.

Liquid bio-fuels like bio-diesel from rapeseed oil or flexi-fuel like bio-ethanol from creamery waste whey or cellulosic wood based feedstock, producing second generation ethanol. Importing ethanol or bio-diesel is not a good solution. It is often made from corn which is very energy intensive and CO2 emitting. It can cause deforestation to rain-forests and food and water shortages in poor countries. It also means importing this fuel like our oil, gas and coal.

Practical solutions for switching to Renewable Energy systems

We use energy in our homes for space heating, domestic hot water and for a myriad of uses of electricity, – such as, lighting, cooking, chilling/washing /drying/appliances, electrical/electronic equipment and motive power, such as pumps and fans. Power use in the home is increasing with the use of more and more new electrical gadgets, and soon we’ll start adding to this electricity demand, by charging batteries at night, where ‘plug in’ EV car transport is approaching reality.

Replacing Fossil Fuels with Renewable Energy Sources (Part 1)

When we compare our existing homes with those of others, especially in central or northern European countries, ours like in Britain, are typically very inefficient in energy performance. They tend to be poorly insulated, wasteful in energy and expensive to keep warm, while many still remain cold, damp, unhealthy and draughty. They are also very dependent on the use of oil, gas, coal or peat, which makes our homes generally very high in emissions of carbon dioxide.

The CO2 emissions from heat and power in all our homes have increased by a whopping 10% in 2008! – Where our average house generated 8.4 tons CO2 per year. This is over twice the European average! The increase in 2008 was blamed on a longer heating season that year than is usual, but it shows how vulnerable our homes are when exposed to the challenges that lie ahead. Will the cold spell that occurred this mid-winter repeat last year’s increase in fuel consumption and emissions? Or, on this occasion, will a large portion of householders have to suffer more from the cold? Because of our economic downturn, will many households have less disposable income now to pay for this increase in fuel demand? Even though energy prices have recently shown signs of coming down here, I believe that as we approach ever closer to the global terminal decline in the production of oil, these reduced fuel prices will surely be short-lived. Especially as other Economies come out of recession, the world demand for oil increases and scarcity of supply drives prices up again. I am convinced that we will see price rises happening again within a very short time, as it did in 2008 where crude oil prices soared to $147 a barrel and gas followed it. This would have continued upwards, only that World economies collapsed and with energy demand, which was brought about partly because of this oil price shock.

What is realistically achievable? Part Two – Targets…..

First: – Getting back to our ’big global challenges’ that need urgent response, these include:

1. Global warming,

A changing climate and deforestation:
- All of these are in need of urgent remedy and contributing to: – increasing surface temperature, rise in sea levels, – accelerating ice-melt, -more extreme, unpredictable and frequent weather events, – more intense floods, droughts, stressing water and food shortages, heat waves and species extinction.

What is realistically achievable?

Having now entered a new year and commenced the 2nd decade the 21st century, – a new era where we face daunting challenges. Besides facing consequences our unprecedented economic setback with all its unfolding hardships, there are much more serious issues facing us all, where there impacts will become more apparent in the early part of this century.

Fuel Consumption in Ireland

Each year Ireland spends €6.5 million on imported fuels, where €1.6million of this is spent of home energy. =25% of Ireland’s total energy requirement and CO2.

Lets Go Green for Christmas

Did you know that Irish families this Christmas will consume an estimated 1 million selection boxes, 1.4 million boxes of biscuits and will pull 16 million Christmas Crackers. All this waste will result in a packaging mountain this Christmas, unless we do our part!

It starts at home

Going green starts at home and our next post from Duncan is going to give an overview of the steps we can take to future proof our homes, from the small and simple to the major changes. To get us ready for this post, over the next two weeks we are going to explain a [...]
